First Claim
Patent Images
1. A bat weight for use on a bat having a knob end, a barrel end opposite the knob end and a taper defined along an outer surface between the knob end and the barrel end, a cross-section the bat weight comprising:
- a) a longitudinal axis, a first opening at a first end, and a second opening at a second end opposite the first end, the second opening being larger than the first opening;
b) a weighted section defined between the first end and the second end, a portion of which further comprising in cross-section;
i) a first layer of material;
ii) a weight;
iii) a second layer of material;
iv) a foam layer; and
v) a third layer of material;
c) an annular retainer ring secured proximate the first end for engaging the bat taper upon advancement of the bat weight across the bat outer surface from the knob end to the barrel end, the annular retainer ring fixing the dimension of the first opening during use and non-use of the bat weight relative to a bat such that the first opening is not adjustable relative to the bat during use an non-use of the bat weight relative to a bat;
d) the weighted section spaced from the annular retainer ring and defined between the annular retainer ring and the second end and further comprising a plurality of separate, spaced apart weights secured around the longitudinal axis; and
e) wherein centrifugal force during swinging of the bat seats the annular retainer ring against the bat taper.

Abstract
Apparatus to add weight to an athletic ball striking bat, having a taper along the bat length, comprising in combination a sleeve sized to extend about the bat at the taper location, the sleeve having associated retention means to engage the bat at a zone along said taper to resist lengthwise removal of the sleeve off the bat during bat swinging, a weight or weights carried by the sleeve.

5. A bat weight for use on a bat having a knob end, a barrel end opposite the knob end and a taper defined along an outer surface between the knob end and the barrel end, the bat weight comprising:
-
a) a longitudinal axis, a first opening at a first end, a second opening at a second end opposite the first end; b) a circumferential inner wall of flexible, expandable material defined along the longitudinal axis between the first and second ends for positioning adjacent the bat outer surface; c) a weighted section defined by a plurality of separated, spaced apart weights arranged around the circumferential inner wall; d) an outer surface defined over each weight for assisting in the gripping and positioning of the bat weight relative to the bat; and e) a non-adjustable retainer ring secured proximate the first end for engaging the bat taper upon sliding advancement of the tubular sleeve across the bat outer surface from the knob end to the barrel end, the retainer ring spaced from the weights along the longitudinal axis of the bat weight, the retainer ring being non-adjustable during use and non-use of the bat weight relative to a bat; f) wherein centrifugal force during swinging of the bat seats the retainer against the bat taper; and g) wherein the weighted section is spaced from the second end such that the second end is axially deformable relative to the weighted section. - View Dependent Claims (6, 7, 8, 9)

10. A bat weight for use on a bat having a knob end, a barrel end opposite the knob end and a taper defined along an outer surface between the knob end and the barrel end, the bat weight comprising:
-
a) an elongated tubular sleeve comprising a longitudinal axis, a first opening at a first end, a second opening at a second end opposite the first end; b) a circumferential inner wall defined along the longitudinal axis between the first and second ends for positioning adjacent the bat outer surface; c) a circumferential outer wall defined along the longitudinal axis between the first and second ends for assisting in the gripping and positioning of the sleeve relative to the bat; d) a layer of foam defined between the circumferential inner wall and the circumferential outer wall; e) a non-adjustable retainer ring secured between the circumferential inner wall and the circumferential outer wall proximate the first end for engaging the bat taper upon sliding advancement of the tubular sleeve across the bat outer surface from the knob end to the barrel end, the retainer ring being non-adjustable during use and non-use of the bat weight relative to a bat; and f) a plurality of separated, spaced apart weights arranged around the circumferential inner wall and spaced from the retainer ring; g) wherein centrifugal force during swinging of the bat seats the retainer ring against the bat taper. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
